By the way, I have pictures of the fabulous 2-rail O-scale scale layout that was once in Lehighton PA...they're not digital however. I believe the layout was called the the Pocono Northern and was featured in an OGR issue, Fred Dole, many years ago. This was a magnificent layout that featured real water features including a thunderstorm and real rain.
It's interesting and not surprising that all the 2-rail layouts mentioned thus far tend towards scale "everything", as opposed to the 3-rail world where whimsy and fantasy blend together.
